Designed by Biber Architects, the US. pavilion is named "American Food 2.0: United to Feed the Planet" and will explore food production, sustainable farming methods, and health and nutrition. Rainwater harvesting as well as hydroponic methods will be used to grow food on the structure's exterior, and solar panels on the roof will power the entire building.

The barn-like structure is designed to evoke a rustic, pastoral vision of the US, but with breezy, perforated walls and an utterly contemporary vibe. Visitors will enter using a boardwalk—made from beams recycled from other American boardwalks—which will wind up and through the space.

And of course it wouldn't be the America without food trucks, which will be clustered around the outside of the structure. No word yet if these will be Italian outposts of some of our more famous American exports—How about some Kogi tacos, or the Big Gay Ice Cream Truck?—but here's to hoping that the organisers are able to deliver an authentic street food experience.
